To convert a string to a long in Java, you can use the parseLong() method of the java.lang.Long class. This method parses the string as a signed decimal long, and returns the resulting long value.
public class IntToByteConversion { public static void main(String[] args) { // Step 1: Define an int value int intValue = 127; // Step 2: Convert int to byte using type casting byte byteValue = (byte) intValue; // Step 3: Display the results System.out.println("Original int value...
To convert anint(primitive integer) value into aString, we can use eitherString.valueOf()orInteger.toString()method. Internally, theformer calls the latter, soInteger.toString()should be preferred. This Java tutorial discusses the following techniques for converting anintto aString, and we’ll co...

To convert a byte array to a hexadecimal string in Java, you can use the following method: public static String bytesToHex(byte[] bytes) { StringBuilder sb = new StringBuilder(); for (byte b : bytes) { sb.append(String.format("%02x", b)); } return sb.toString(); } This method ...
To go the other way round and convert decimal to hex in Java, you can use the utility method Integer.toHexString(). If you have the value that you want to convert in an int variable, then you can simply call: int i = ... String hex = Integer.toHexString(i); System.out.println("...
